Hi,
had a small progress and now new problems.
Connection to 149.154.159.134 worked today: SamyGO app was installed (ChannelInfo also).
After that i started SamyGO (screen went black for a few seconds and came back into SmartHub).

Now my current problem:
Connecting to TV by telnet or ftp fails. ftp and telnet return "connection refused". I've tried different ports for telnet (23, 1023, 2023).
I've verified that there is NO firewall rule denying the traffic, so firewall is no problem here.
I've also switched TV off and on again (and then restarted SamyGO) to no avail.

Anyone an idea why i cannot connect to TV by ftp or telnet ?
Again, TV is on FW 1026; could this be the source of this problem ? Anyone out there with FW > 1020 who can successfully connect to TV by ftp or telnet ?

Any idea, pointer, link, help, even just a "moooo" are highly appreciated.

Thank you very much for the great tutorials!!
It worked perfect with an downgread to the samygo-Firmware and then installing the SamyGo-App on my UE37D6500.

Now I have a little Problem. We would Like to analyze the newest used Browser version on the TV. The one running at the moment is quite old, from ~2011. Is there any way we can update / upgrade the Firmware and/or Browser and still using the root shell?

Im perfectly fine with donating to SamyGo for any solutions, where we have a root shell on the newest version.
Thank you very much for any help!!

Cheers!

Hey Guys,
I solved my Problem from above ^ and got the (root) shell on the newest firmware (27) by downgrading the Firmware to 13 (factory reset or as shown in this tutorial), attached my Shell to the browser Software on the tv, which is one of the only places which does not get flashed when upgraded. Afterwards i made the firmware upgrade as usual and get the shell by starting the browser.
Its a very simple process, if your still interessted into the details, please write here and i post the scripts.

1. We rooted the TV from an old firmware with the SamyGo tutorial. Thanks so much for this!!

2. If you wanna keep your root shell persistent, you need to put it somewhere where you can start it and where it does not get deleted.
By looking into the Firmware-Upgrade Images we saw, that basically everything gets overwritten beside the installed Apps.
Here the "native" apps from Samsung are apperantly allowed to use "real code". So we picked one of them. The Web-Browser App was perfect for this, couse we found an launcher.sh script in the bin folder. The App was for us at the following location: "/mtd_down/widgets/normal/20111000001/".

3. Make it persisten. First we updated the browser to the newest version, so we avoid an update after we changed some stuff at the browser.
Next we need a tool which allows us to make a bind shell after all the Samy stuff is gone. So we were preatty lazy and copied the busybox from the samy binaries. YOU NEED TO COPY THE busybox FROM THE SAMY BINS not the one form /bin/busybox couse this one has less functions.
So copy (cp) the busybox from your SAMY bin folder to:
